Not quite so...if i remember correctly there were some lore entries where oryx or his brood battled some races for millennia. But a good thought.

I thought that was when he didn’t use his full power?

Also im not quite sure what you mean about that. According to sword logic he wouldnt ever have been at full power unless he was the last being left in the universe. Or do you mean he wasnt using all availible at that moment? Do we even know what that amount would be? Good points. Nice to see mature people speaking about lore without getting hateful.
